How often do you service the pump ?   We take very good care of this particular pump . It's a crucial part of our process . We clean it and flush it through at the end of every shift , We check the high pressure seals , recalibrate the gauges and lubricate all moving parts weekly . We replace the gaskets every month .   How do you decide how often these things need to be done ?   Well , from experience we can predict the lifespan of different components . We try to replace components before they fail or wear out . This prevents the equipment from breaking down . It also saves us a lot of trouble !
